Todd made the best fake strange look he could and walked up to the 6'11" brunette.
"Excuse me," He approached her as she went further down the aisle, so not to be seen, "but do you know what just happened to you?"
He peered up from his own 5'10" height.
She looked down with a scared look on her face and shook her head. "I was just looking at this book about physics and I just grew all of a sudden. Did you see it happen?"
"Yes. I had no idea what was going on. Are you okay? Do you feel fine?"
"I feel big," she smiled uncomfortably. "Did you see anything strange happen to cause this, um-- we have physics together but I don't recall you name..."
"Todd. No, I didn't see anything but you. What is your name? It's an M or an S name, isn't it?"
"Nancy."
"Okay, Nancy. I knew it from physics, I think. Do you feel sick or anything?"
"I'm not used to being this far off the ground is all. I should be okay, though. My clothes took a beating, though."
She fingered some shreds.
"I'm not as tall as you are, Nancy, but I have a long coat you can probably wear to get where you need to go. A library's a weird place to be changed so suddenly."
Nancy smiled shyly and nodded.
"I should probably go home or to the doctor or something. You saw this happen, would you like to tag along?"
Todd felt bad inside about lying, but thought it would be okay. This might turn into the strangest pick-up situation in history.
